The Huashixia-Jiuzhi highway opens to traffic in northwest China's Qinghai Province, on November 13, 2017. It has the world's highest tunnel that runs through unstable rocks. The tunnel, 4,400 meters above the sea level and 9,065 meters long, is a part of the highway linking Qinghai with northwest China's Xinjiang Uygur Autonomous Region and southwest China's Sichuan Province.
